At the same time that the AFL-CIO is accusing her of being too close to George Bush, a new US Chamber of Commerce TV ad, part of a six-state spending spree on behalf of endangered Republicans, is attempting to link Susan Collins with Barack Obama.

The ad features the same bright blue background that is used on Obama's website and in his campaign advertising. It also uses Gotham (or another sans-serif font that is strikingly similar), the typeface closely associated with the Obama campaign.

The ad is also on the subject of health care, one of Obama's key issues. Of course, the Chamber is congratulating Collins for taking a position diametrically opposed to that of the Democratic nominee.
